Fake birth certificates, ghostwriters, teleprompters, a teenage trip to Mars, and more of the most paranoid and bizarro Obama conspiracy theories out there.

Barack Obama's presidency has been an inspiration to many Americans—especially nutjobs. Ever since the first-black-president-to-be appeared on the national political stage, a cottage industry of conservative conspiracy theorists has churned out bizarro, paranoid, and just plain racist effluvia—some of which has trickled into the political mainstream. Below, we've charted some of the Obama-baiters best (i.e., worst) work. (Scroll down for more detailed descriptions of the conspiracy theories in the diagram.)

The Conspiracy Theories

Disclaimer: It should go without saying that none of these are true. Follow links at your own risk.

Obama is a secret Muslim: This one began right after he took the stage at the 2004 Democratic convention, with chain emails alleging his "true" religious affiliation. The rumor soon found its way onto the popular conservative online forum Free Republic, and took on a whole new life in the years to come. Related: Obama secretly speaks Arabic, attended a madrassa as a kid in Indonesia, referred to "my Muslim faith" in an interview, and was sworn in on a Koran.Steve Brodner

Obama is bringing 100 million Muslims to America: Avi Lipkin and his PR outfit Special Guests claimed to have evidence of a scheme to bring roughly 100 million Muslims from the Middle East into the United States, converting the country into an Islamic nation by the end of Obama's second term and making it easier to obliterate Israel.

Obama once aided the mujahideen: Harlem pastor and professional race-baiter James David Manning contended that in his younger days, Obama went undercover as a CIA agent to facilitate the transfer of cash and weapons to the Afghan mujahideen in the '80s, thereby aiding what would become the Taliban.

Obama is in the pocket of the Muslim Brotherhood: Billy Graham's son Franklin wants you to know that Obama is allowing the Muslim Brotherhood to take over the federal government.

Obama redecorated the Oval Office in Middle Eastern style: Driven by his fierce sense of anti-American interior design, Obama got rid of the red, white, and blue decoration scheme in his White House office.

Obama married a Pakistani guy:World Net Daily correspondent and conspiracymonger extraordinaire Jerome Corsi posted a videoin which he claimed to have "strong" evidence that Obama was once married to his college roommate from Pakistan. The smoking gun: Photos of the chums in which the future president is "sitting about on the [Pakistani roommate's] lap." Related:For years Obama wore a gold ring on his left hand. Was it his gay-wedding ring?

Obama's ring has a Koranic verse on it: The very same ring, which Obama now wears as his (straight) wedding band, is allegedly emblazoned with a key phrase in the Islamic declaration of faith: "There is no god except Allah." (It's not.)

Obama was funded by a Saudi prince: Another fairy tale courtesy of Corsi: In late-'70s Chicago, Obama secured political and academic funding from a variety of sketchy Arab sponsors, including a Saudi prince. Which may explain why President Obama bowed to the Saudi king when they met in 2009.

Michelle's "whitey" tape: During the 2008 campaign, rumors surfaced that a video of Michelle Obama using the word "whitey" would be released to sink her husband's campaign. It's never materialized. Related: The time Glenn Beck called Barack Obama a racist.

Obama is the son of Malcolm X: Because, you know, black people. This charmer popped up on Atlas Shrugged, Pamela Geller's anti-Muslim website. (Geller is also known for obsessing over Shariah turkeys she believes are destroying Thanksgiving.)

Obama is the son of Frank Marshall Davis: The conspiracy film Dreams From My Real Father espouses the theory that Davis, a leftist activist, was not only Obama's ideological mentor but his biological father. Related: Obama got a nose job to make his nose look less like Davis'.

Obama's mom and dad were communists: That would be his real father, Barack Obama, Sr. And you know that communism is an inherited condition.

Obama's ghostwriter was Bill Ayers: Conservative commentators claimed they uncovered evidence that ex-Weatherman Bill Ayers was the true author of Obama's 1995 memoir Dreams from my Father. Beyond their shared radicalism, Obama asked Ayers to help because he had writer's block.

Obama trained to overthrow the government: In 2008, leading Obama conspiracy theorist Andy Martin declared on Fox News' Hannity's America that the then-presidential candidate had trained for "a radical overthrow of the government" during his time as a community organizer in Chicago.

Obama wouldn't say the Pledge of Allegiance: During the '08 campaign, Obama was rumored to have refused to say the pledge during a town hall meeting. A photo of the incident was actually taken while the national anthem was being sung.

Obama removed the flag from Air Force One: …and replaced it with his campaign logo.

Obama ordered soldiers to swear allegiance to him: In April 2009, a clearly satirical report detailing how secretary of defense Robert Gates was growing "extremely frustrated" with the White House's plans to scrub the Constitution from the military oath of loyalty made the rounds on the right-wing blogosphere.

Obama secretly gave away American islands to Russia: Texas House candidate Wes Riddle endorsed this theory and noted the relinquishment as grounds for impeachment. However, the seven Arctic islands were actually given away in 1991 by President George H.W. Bush.Steve Brodner

Obama caused the recession—in 1995: According to a recent Daily Caller story, Obama's efforts to force banks to lend to African Americans in the mid-'90s led to the subprime mortgage crisis that killed the economy in 2008.

Obama's coming for your guns: Extreme gun-rights outfits, along with Sen. Rand Paul (R-Ky.), alleged that the Obama administration is supporting the (nonexistent) United Nations Small Arms Treaty, which would lead to nationwide gun confiscation. Unfounded fears of gun confiscation have multiplied since the Newtown massacre.

Obama's coming for your gold: This theory was floated by Glenn Beck—and the gold company he shilled for.

Obama is planning FEMA concentration camps: Again with the camps. This theory got a big boost from Glenn Beck (who claims he didn't mean anything by it). Related: An executive order titled, "National Defense Resources Preparedness," was issued in the middle of March 2012. Conservative commentators saw it as a martial law power-grab that allowed the president to commandeer farmland, steal everyone's food, and draft any American into slave labor for a war of aggression against Iran. Also, he has a "secret vault" at Interpol's headquarters for imprisoning Americans. (Chuck Norris is on the case.)

Obama caused the BP oil spill: Conspiracy-minded radio host Alex Jones promoted the theory that the Deepwater Horizon spill was all part of the administration's plans of oil nationalization and global government.

Obama was behind the Aurora massacre: In July, Gun Owners of America blasted out a press release claiming that the mass murder at a movie theater in Aurora, Colorado, was suspiciously timed. "Someone in Washington" was probably behind it, paving the way for Obama-led firearm confiscation and "government genocide."

Obama personally caused Hurricane Sandy: It wasn’t global warming that made Sandy so intense; it was Barack. Alex Jones' site reported the president engineered the storm using a Pentagon weather modification project. The mayhem caused by the hurricane would afford Obama the opportunity to score points by briskly managing disaster relief a week before the election.

Obama had Andrew Breitbart killed: In March 2012, conservative media impresario Andrew Breitbart died of heart failure. Less than a month prior to his death, he had announced that he had uncovered footage of Obama's formative years as a radical. So obviously, Obama had him offed. (The tapes were later revealed to contain things like a young Obama hugging a black college professor.) Related: People—like a Rod Blagojevich fundraiser and an Obama impersonator—died between 2008 and 2012. Obama was in office between 2008 and 2012…coincidence?!?!

Obama spiked the jobs report: "Jobs truthers" (like former GE CEO Jack Welch and Florida tea party congressman Allen West) accused the Obama administration of cooking the September unemployment numbers to manufacture a rosier picture of the economy and boost the president's chances of reelection.

Obama faked bin Laden's death: Since no photographs of Osama bin Laden's corpse were produced, the Al Qaeda leader must still be out there. Fox News' Steve Doocy and Andrew Napolitano entertained the idea that Operation Neptune Spear was merely a ploy to revive Obama's sagging approval ratings. Related: Obama was photoshopped into the iconic killing-OBL White House photo.

Obama's plan to fake an assassination attempt: A false-flag operation would create urban tumult and give Obama the pretext to declare martial law, thus suspending democracy, postponing the 2012 election, and prolonging his stay in office. The theory was flagged by Tenn. State Rep. Kelly Keisling, among others, after circulating online.

Obama's planning a third term: The dust from the 2012 election had barely cleared when this one popped up.

Obama the brainwashing hypnotist: As a master of neurolinguistic programming, Obama convinced Americans to vote for him via subliminal messages. Related: Rush Limbaugh pondered if hypnosis was the reason that so many Jewish voters were in the bag for Obama. In October, Georgia GOP lawmakers held a briefing on the president's secret mind-control plot.

Obama's teleprompter: Obama's eloquence is a myth! The 44th president is incapable of speaking in public with his teleprompter.

Obama had a ghostwriter for everything: Jack Cashill over at WND had a hot scoop on how Obama's love letters to his college girlfriend were ghostwritten.

Obama's anti-Semitic poetry: However, according to the American Thinker, Obama's ghostwriters did not write his youthful poem "Underground," which compares Jews to fig-eating underwater apes and echoes Koranic verse.

Obama's exiled lover: Obama was supposedly fooling around with an attractive young staffer from his 2004 Senate campaign. Michelle Obama had the temptress packed off to the Caribbean before the '08 campaign.

Obama's crack cocaine/gay sex/murder orgy cover-up: In 2008, a small-time conman named Larry Sinclair and his kilt-wearing lawyer held a press conference to tell the world of the future president's murderous, drug-and-sodomy-fueled crimes.

Obama's campaigns were funded by drug money: During an October conference call organized to oppose pot legalization, a writer from Lyndon LaRouche's magazine asked about "reports [that both Obama's] 2008 and 2012 presidential campaigns have been financed in part by laundered drug money."

Obama is the Antichrist:Obviously. Related: If you play his 2008 Democratic nomination acceptance speech backwards, you can hear him instruct listeners to do Satan's bidding.Steve Brodner

Obama is a lizard overlord: According to codes hidden in Biblical verse, Obama is a reptilian humanoid. This idea has found its way on to some right-wing radio shows, and two Daily Caller reporters recently published a (satirical?) e-book on the topic titled, The Lizard King: The Shocking Inside Account of Obama's True Intergalactic Ambitions by an Anonymous White House Staffer.

Obama's adventures on Mars: As a teen, Obama participated in a CIA initiative to teleport to Mars using a top-secret "jump room." Self-described time travelers William Stillings and Andrew Basiago claim to have met the future POTUS at American space bases on the Red Planet. In early 2012, a spokesman for the National Security Council actually acknowledged these claims, and issued a fairly convincing denial.
